The intertwining of Western and Indigenous worldviews in education – An Aotearoa New Zealand case study in marketing education
No full textThis session explores the integration of Te Ao Māori (the Māori worldview) and kaupapa Māori (Māori ideology) in education practice, within the marketing discipline. The authors’ empirical investigation on marketing practitioner’s perspectives on the use of Māori cultural elements highlighted a gap in existing education offerings, which saw the development of a bi-cultural marketing course. However, scaling this in a way that is respectful and student-centric remains a challenging endeavour for Indigenous and non-Indigenous educators alike. This session will draw out practical insights for those wishing to bring together differing, but complementary, knowledge streams in marketing and beyond
Investment under anticorruption: Evidence from the high-profile anticorruption campaign in Vietnam
Full text linkGiven Vietnam's current anticorruption campaign and its distinctive context of decentralized governance and public sector dominance, this paper investigates how anticorruption efforts affect corporate investment behaviour during 2006 and 2019. Using a novel text-based measure of anticorruption and comprehensive firm-level datasets, we uncover a consistent pattern that firms tend to delay investments in response to heightened uncertainty triggered by anticorruption activities. This strategic hesitation reflects a rational response to avoid potential regulatory and political uncertainty, and holds across a wide range of robustness checks, including alternative model specifications, variable definitions, and advanced estimation techniques such as system GMM and entropy balancing. Our findings also reveal that anticorruption campaigns significantly reduce informal business costs—particularly bribery, thus highlighting institutional improvements and a more transparent business environment. Notably, while public sector investment efficiency improves under the campaign, private firms show no significant efficiency gains, underscoring the asymmetry in how reforms affect different ownership structures. By bridging institutional reform with corporate finance, the study offers new insights into the channels through which anticorruption influences firm decision-making, governance, and political strategy. This research fills a critical gap in the literature, demonstrating that anticorruption is not merely a legal or ethical issue, but a transformative force in corporate investment dynamics

No full textArbuscular mycorrhizal fungal symbiosis in New Zealand ecosystems: challenges and opportunities.
No full textArbuscular mycorrhizal fungi (AMF) are obligate biotrophs that form a symbiotic and mutualistic relationship with most terrestrial plants, playing an important role in plant growth, nutrient acquisition, and ecosystem stability. This review synthesizes current knowledge on AMF colonization in plants within New Zealand ecosystems, including the challenges and opportunities of molecular identification techniques used in characterizing AMF communities in natural and managed systems. The ecosystem services provided by AMF, such as improved growth parameters, enhanced nutrition, and disease control, are discussed in detail, highlighting their significance in sustainable agriculture and natural ecosystems. Additionally, the role of AMF in invasion ecology was examined, revealing their dual potential to either facilitate or hinder invasive plant species. Despite significant advances in understanding AMF biology, future research is needed to explore the underlying mechanisms of AMF-plant interactions and to address the challenges caused by changing environmental conditions. This review focused on the importance of AMF in promoting ecosystem resilience and suggests avenues for future research to harness their full potential in agricultural and ecological contexts
Effect of lactic fermentation and matrix on phenolic content, bioaccessibility, and scavenging activity of beetroot beverages
Full text linkWith the rising interest in fermentation techniques and the FAO’s advice to increase fruit and vegetable consumption to lower disease risk, this study investigates the fermentation of two beetroot beverages: a low-fiber juice and a high-fiber puree-based beverage. The lactic fermentation process enhanced the free phenolic content in both juice and puree-based drink (from 2.37 to 4.83 mg/g and from 2.44 to 6.56 mg/g, respectively) and the antioxidant activity in the beetroot juice (from 19.7 to 45.99%), as assessed by colorimetric assays. The findings reveal no correlation between free phenolic content and antioxidant activity, suggesting that other factors, such as the structure of phenolics or the presence of compounds, like organic acids, play a role in antioxidant activity of beetroot beverages. Notably, although fermentation increased free phenolics, the juice exhibited decreased in vitro bioaccessibility of phenolics after fermentation (from 90.07 to 61.35%), while the puree showed an increase (from 63.99 to 92.14%). These observations highlight the dualistic role of fiber-phenolic interactions during fermentation: acting both as a protector against phenolic degradation and a barrier to intestinal absorptio
Genetic diversity of Saccharomyces cerevisiae isolates from organic Pinot noir wine production in New Zealand
Full text linkSaccharomyces cerevisiae is the major yeast species involved with the production of alcoholic fermented beverages, including wine which is a major export commodity. The species exhibits significant interstrain diversity, which influences the character of wines produced. Spontaneous fermentation is an uncommon production method, but such organic approaches are increasing in consumer appeal. However, the level of interstrain diversity in such production systems is infrequently characterised, yet the influence of individual strains on the organoleptic character of wine is well recognised. We used a DNA-based Inter-Delta Typing (IDT) method to elucidate the genetic diversity and population dynamics of Saccharomyces cerevisiae isolates from an organic Pinot Noir winemaker in Waipara, Aotearoa New Zealand. One hundred and forty-three S. cerevisiae isolates from key fermentation stages during the production of organic Pinot noir wines produced by spontaneous fermentation were differentiated by IDT analysis into 95 different genotypes, of which 21 were observed more than once. Three IDT genotypes were observed among each of the fermentation stages yielding isolates, although none individually reached a position of dominance. The diversity observed may reflect both the biodynamic nature of the organic production system, including climatic factors, as well as the relative stage of maturity of the New Zealand wine industry compared with the global winemaking landscape. The impact of this diversity on the organoleptic properties of wine produced in this region using organic, spontaneous fermentation approaches requires further study. The value of IDT to characterise the genetic diversity of S. cerevisiae is supported, and may have value in identifying strains of particular significanc
The microbiome associated with grapevines escaping trunk disease: A potential source of beneficial microorganisms for disease control
No full textGrapevine trunk diseases (GTD) represent a major challenge to viticulture in New Zealand and globally. Due to the limited availability of effective control strategies for these intractable diseases, identifying alternatives, including biological control is an increasing focus. Vines that remain healthy in a background of heavy GTD pressure have been observed in some New Zealand vineyards. This study surveyed vineyards for the presence of grapevines escaping GTD, referred to as disease escape vines. Wood tissue samples were collected from these putative disease escape vines and the surrounding diseased vines. The fungal and bacterial communities were characterised using DNA metabarcoding of the ribosomal internal transcribed spacer 1 (ITS1) and 16S ribosomal RNA gene. The results showed that the status of the vine as either GTD escape or diseased was a significant determinant of the bacterial and fungal microbiome structure of the grapevine trunk. The bacterial taxa Pseudomonas and Hymenobacter and the fungal taxa Aureobasidium, Seimatosporium, Cladosporium, and Rhodotorula were differentially associated with GTD escape vines. In contrast, the GTD pathogen Eutypa lata was associated with diseased vines. Based on the DNA metabarcoding results and functionality testing, Aureobasidium pullulans, Seimatosporium vitis, and seven Pseudomonas isolates were selected from the cultures retrieved from the disease escape vines for inclusion in a synthetic community (SynCom). Separate and combined fungal and bacterial consortia were
assessed in planta against the GTD pathogens E. lata and Neofusicoccum luteum. After 3 months, the bacteria successfully established within the grapevines, with the combined bacterial and fungal consortia treatment resulting in significantly shorter lesions than the pathogen controls. These results highlight the potential for using selected microbial consortia as a promising strategy for controlling GTD pathogens in planta
Agri-food transformation – how can value chain actors foster climate resilience?
No full textClimate change and environmental degradation pose significant challenges to agri-food supply chains, threatening the resilience of both businesses and farmers. These challenges are compounded by social and economic injustices, such as disparities in land access and unequal exchange, which are prevalent along often lengthy supply chains. Addressing these interconnected issues requires a holistic and collaborative approach involving diverse stakeholders, including farmers, government bodies, researchers, and industry participant
